De-Specialist Works were awarded the demolition, structural alterations and cut & carve package at 181 Queen Victoria Street. The refurbishment goal was to transform the existing modular office layout into an open plan setting.
To achieve this, a third of the building was cut, separated and rebuilt in steelwork with a mixture of lightweight concrete and timber decking – this provided a new structure in place of the previously existing light well.
Internally, significant temporary works were designed and installed, to allow us to remove structurally integral walls and install new permanent solutions to assist in the forming of the new open plan lay out.
De-Specialist Works also carried out a groundworks package to the basement, modernising the drainage system and also constructing a new lift pit for modernised lift facilities.
The primary Project challenge was its location, adjacent to Blackfriars train station. Logistical issues twinned with the complexity and sequencing of the temporary works ensured a challenging scheme from start to finish. The vicinity of the station required close liaison with Network Rail for all crane lifts for the new structural steelwork erection. The ongoing temporary works including the necessary AIP required further liaison with the Local Authority highway engineers to ensure structural soundness at all times.
Due to poor ground conditions as a result of being located on the reclaimed area of the River Thames, the existing foundations were required to be re-used, this required further complex temporary works and additional design input to ensure the new construction did not exceed the limitations we were working with.
